Use of Trained Dog in Aggression Management

I thank God that where I work, this therapy or treatment have never been mentioned and would not be mentioned.
Nature made it that animals should be under man, I think it most cruel and inhumane to use dogs no matter what they are trained to do , to treat human beings especially in this context of aggression management. To me, this might escalate the situation, and even if it does have positive effect, it would be short lived. Where is our compassionate care? The mentally sick also appreciate care and show of empathy and love. This has worked in many cases. If they are at the state of unreceptiveness to care, medicate them.
